Application filed December 1, 1910. Serial No. 595,094.

To all whom it may concern:

-Be it known that I, CHARLES SGIIENCK, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lubricators for Elevator-Guides, of which. the following is a full, clear, and exact description.

The invention relates to lubricators for elevator guides of the type adapted to be carried by'the car to automatically lubricate the guides as the car travels. Lubricators of this sort have heretofore comprised oil receptacles with wicks leading; therefrom and suitable springs for yieldingly holding the Wicks into engagement with the surfaces of the elevator guide. Such prior constructions are efficient, since the wicks economically feed the oil by capillary attraction, and since a number of wicks may be used to lubricate the surfaces of the guide. But

in such constructions the wicks directly engage the guide surfaces and hence, are rapidly worn out.

In accordance with the present invention, the lubricator is provided with shoes which are spring pressed into engagement with the surfaces of the guide and wicks leading from theoil receptacle feed the oil to the guide engaging surfaces of the shoes. These shoes are formed of non-abrasive material, such as fiber, soft metal or the like, so that they will not injure the finished surfaces of the metal guides. Preferably, also, the shoes are provided with wick receiving openings ex'tending.to the guide engaging surfaces thereof and the wicks are securely held within the openings and are protected by the shoes so that they cannotwearout.

The preferred embodiment of the invention is hereinafter set forth, illustrated in the accompanying drawings and the essentials of the invention are more particularly pointed out in the appended claims.

In the drawings, Figure 1 is an elevation of the improved lubricator with parts in section on the line 11 of Fig. 3. Fig. 2 is a vertical section on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section on the line of Fig. 1 and Fig. 4 is a horizontal sectiononthe lines 44 of Figs. 1 and 2.

. As shown, the body of the lubricator preferably comprises a U-shaped receptacle 10 adapted to extend about the elevator guide 11, as most clearly shown in Figs. 3 and 4. The receptacle is provided at its lower end with perforated ears or, lugs 12 for receiving suitable fastening screws by which it .is secured to the guide engaging shoe or other suitable part of the car in.proper relation to the guide. A removable cap 13 is provided for closing the upper end of the receptacle. As shown, this cap is connected to the body of the receptacle by a chain 14 and is held in position upon the upper end of the receptacle by a suitable fastening device. In the,form shown, the fastening device comprises a projecting screw 15 that is engaged by a bifurcatedlug 16 on the cap and a clamp nut 17 threaded on the screw and arranged to engage the lug 16. The recessed portion of the U-shaped receptacle is .provided, at its lower portion, with walls 18, so that a reservoir is provided for the lubricant or oil.

The guide engaging shoes 19 and 20 are preferably mounted within the upper portion of the receptacle upon a series of pins 21 which are fixed to the walls of the receptacle and project inwardly therefrom. As shown, the pins are square in section and the shoes 19 and 20 are provided with similarly shaped openings, so that the latter are held against twisting. The shoes are provided with broad guide engaging faces which fitupon and slidably engage the surface of the elevator guide. In the form shown, the shoes are provided with fiat sur-' faces arranged to engage the corresponding surfaces of the guide 11, the shoes 19 engaging-the side faces of the guide and the narrower shoe 20 engaging the edge face thereof. A series. of springs 22 coiled about the pins 21 extend between the walls of the receptacle 10 and the shoes 19 and 20, so that the latter are pressed into engagement with the elevator guide."

The shoes 19 and 20 are preferably formed of fiber, but may he formed of soft metal or other suitable non-abrasive material which is relatively soft as compared with the steel or wrought iron elevator guide.

A series of wicks 23, formed of suitable textile material, such as heavy flannel or the like, lead from the oil reservoir in the lower portion of the receptacle and extend 4 l through suitable openings in the shoes to 'f -the guide engaging surfaces thereof. These .so'penin'gs preferably comprise grooves formed "in the guide engaging faces of the shoes 19 and 20 and within which grooves the upper portions of the wicks are The narrow block 20 that engages. the'edge through face of the guide has a vertical groove 26 1n its face, the lower end of which communicates with an inclined hole 27 extending end. The side edges of the grooves 24 and 26 are preferably under-cut, that is to' say the openings of the grooves upon the surfaces of the wick-holders are narrower than the main portions thereof, as lndicated-in the drawings. These grooves are of such size that, when the wicks are compressed therein, the latter are securely gripped and held in. proper relationto the shoes..and to the elevator guide.

In operation, the guide engaging surfaces of the shoes or wick-holders l9 and 20 and the surfaces of the guidell are at all-times oilor lubricant thoroughly coated with the which is drawn from .the reservoir by -wicks 23. The shoes, as stated, are preferably formed offiber or other suitable non abrasive material, which is relatively soft as compared with the steel elevator guides, so that the surfaces of the guides are not injured by'the rubbing contact thereof. The wicks are so arranged that they cannot readily wear out and do not have to be frequently renewed. The arrangement of the grooves 2 1 and 26 in the wick-holders or shoes is such that the wicks 23 all extend from the ,outerportion of the oil receptacle inwardly toward the. shoes and the upper portions of the wicks are compressed and securely gripped within the grooves of the shoes and cannot be displaced from proper position. The portions of the Wicks 23 in the oppositely inclined groov 24 of the shoes 19 rub over the side bear ng faces of the elevator guide ..1 and serve to deflect the oil toward the opposite edge portions of these faces and thus properly distribute it over all portions thereof.

It is obvious that numerous changes may be made in the details set forth without the departure from the essentials of the invention as defined in the claims.
